SPECIFICATION formingpart of Letters :Patent No. 294,783, dated March 11, 1884.

i Application filed March 14, 1883. (No model.)

To all whom, it may concern:

Be it known that I, JAMES Hose, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain iiew'and useful Improvement in Gan-Machines, of which the following is a specification.

My invention relates to the manufacture of metallic cans, and it consists in the arrangement and employment, in a can-making machine, wherein a presser mechanism and squeezing, forming, or crimping slides are conjointly employed, of the presser mechanism hereinafter described and claimed, which is essentially intended to be operated independently of the mechanism which actuates the squeezing, forming, or crimping slides, so that the main bodyof a can may be thereby cor-` rectly located in position in connection with the top or bottom, which is to be xed thereto before the squeezing, forming, or crimping mechanism is drivento its work, and so securely held while such squeezing, forming, or crimping'work is -being done.

In the accompanying drawings, Figure 1 is a perspective view of a-foot can-press embodying my improvement; Fig. 2, a detail of same.

In the ordinary can-press, in which the presser mechanism and slides C C C C are con-` nected to one actuating mechanism-for instance, in a foot-press, to the treadle A-Pthe vpresser-plate and slides act simultaneously or so nearlyso that the presser mechanism frequently fails to reach its proper working position before the slides commence their work, interfering with the necessary function of the presser, and resulting in a deficient joint which renders apart, if not the entirety, of the material of the can worthless for use.

It being customary to bevel or otherwise shape up the joint-edgcsof the parts D and d preparatively for the work' of the press, it is frequently the case thatthe part D or d is defectively formed, and that ,difficulty of a greater or less degree is encountered in readily and correctly coaptating such parts for the work4 of the squeezing or crimping slides, such defect and difficulty not being noticeable where there is simultaneous action -of the presser and squeezing mechanism until it is too late to remedy the resulting imperfect work. It isobvious, therefore, that a presser mechanism acting independently of the squeezing-slides greatly facilitatesv the correct doing o'f such work, overcoming the expense incident to the loss of time and waste of material consequent from imperfect joints by enabling the operator to properly locate and rmly hold the parts together which are to be united, 6o and intelligently drive the slides to their work at the proper moment, withth'e certainty that such work will be done beyond the possibilityT of imperfection or accident.

As is shown in the accompanying drawings, I employ a vertically-acting bar, c, which carries at its lower end a hinged presser-plate, c, the bar being hinged at its upper end to a lever, c?, which is pivoted to a bracket, E, which is adjustably connected by a bolt, c, to an up- 7c right, F, extending from the table H of the machine, the bracket being provided with a cani-surface, g.

To the outer end of the lever c2 is attached a spring, c3, the lower end of which is fastened to aprojection from the table H, or some other suitable connecting-point.

At or near the longitudinal center of the lever c2 is pivoted a rectangularly-sh ap ed lever, G, provided at its eXtreme lower end with a So friction-roller, g, which works upon the camshaped portion g when said lever is moving from or returning to its normal position.

The action of my machine is as follows: A formed-up top or bottom, d, is placed upon the anvil h, and the cylindrical or main portion D of the can is placed on top thereof,. so as to drop with the 'formed-up margin. of such part d. A forward movement of the long arm of the lever G carries the sh'ort arm 9o v up the cam g', elevating the rear end of the lever c2, and depressing its forward end, so that the bar c is driven downward, clamping the presser-plate c upon the end of the cylinder D, which it forces firmly in position in and upon the part d. The lever G being held rigorously in such position, theA slides C C C C are driven to their work by the treadle A, to which they are connected by the rod B, the slides impinging upon the turned-up edges of ioo the part (l, which are thereby lapped over the 1`oii11ed-up edges of the part D, thus forming the necessary joint.

The connection of the bracket E to the up- 5 right F, as shown7 enables its adjustment for work upon cans of large or small size.

Iam aware that can-machines embodying a presser mechanism and forming; or Crimping' slides operating,r independently have heretofore been used; but my improvement differs essentially therefrom.

I therefore claim and desire to secure by Letters Patent-- In combination with the forming or crimp# ing mechanism of a eansmaehine, the independently-operating presser mechanism composed of the bar c', provided with a foot or plate, c, bracket E, having Cam-surface y', lever 6*', pivotal to said bracket, and lever G, pivotedto lever ci, all arranged and operat ing ihstantially as and for the purpose (lescribed.
